Harry Kroto is a chemist, professor, Nobel Prize winner, and the discoverer of the buckyball!

Harry Kroto

Sir Harold Walter Kroto shared the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley for the discovery of the "buckyball", the "molecule" shaped like a soccerball made of  60 carbon atoms. Originally from England, Prof. Kroto has been a Professor of Chemistry ... Read More...

Heather Clark is a nanoscientist at Draper Laboratories who works on developing special tattoos made of tiny little nanoparticles to measure blood glucose so that people with diabetes can better measure their blood sugar levels. How cool is that?

Liquid Armor

by

Can nanotechnology help to protect soldiers in combat? Maybe some day. Scientists are working on something that they call liquid armor. In the old days, knights would walk around with really heavy clunky armor. That was OK, but it made it hard to do ... Read More...

Work With Things You Can’t See

by

Nanoscientists use powerful microscopes called scanning probe microscopes to “see” atoms and molecules. In school or maybe at home you probably used an optical microscope. With those microscopes you can see cells. Scanning probe microscopes are a lot different than optical microscopes. Instead of using lenses and light ... Read More...

The Most Famous Molecular Shape

by

Think of the shape of a molecule. What image pops into your head? Probably the double-helix shape of DNA. It is so familiar that when you see a double helix, you immediately think of DNA. The double-helix shape of DNA was discovered by Francis Crick and ... Read More...

How Molecules Shape Up

by

Do molecules have a real shape or are they just some kind of random blob like a piece of jello? Well, molecules do have shape (even the molecules that make up jello have shape) and their shape is important. Some molecules, like enzymes (which are ... Read More...

Bonds Hold Atoms Together

by

The bonds that hold atoms together to form molecules are called covalent bonds. They are pretty tough and not easily made or broken apart. It takes energy to make the bonds and energy is released when the bonds are broken. Trees take light and use it ... Read More...

Nano Tattoos

by

If you have a certain kind of diabetes you already know this—getting a tiny bit of blood and then testing it for glucose is a daily ritual. People with diabetes have to test their blood a lot because if their blood sugar goes out of ... Read More...

This, believe it or not, is a microscope.  It can help us see very small particles like molecules by feeling the particle with the tip of its needle.

The tip of an AFM microscope is made of silicon and is only a few nanometers wide at the sharpest point. That’s extremely sharp!

Seeing Shapes of Molecules

by

How do we know if a molecule has a shape? Well, there are various ways, but the most direct is to use a very powerful microscope like the atomic force microscope. That is what Seth Darling used to “see” his surfaces and all those shapes ... Read More...

Look at this picture, what do you see? A forest with many little trees? Think again! Sometimes pictures like this one can trick us. This image shows an unexpected result from an experiment— clusters of gold nanostructures shaped like tiny trees. The scientists didn’t know they were making trees, but it sure looks pretty cool.

A Tiny Forest?

Everything we do in science is always predictable, right? It always comes out the way we plan it. Put it on a piece of paper and it happens? WRONG! Most of the time science is just that: science, research, you set things up and you ... Read More...
